1x1x2 RoadblockAlthough it tries to look like a 1x1x2 this puzzle is a 1x2x3.
1x1x4A stupid cuboid built just for the sake of completeness.
1x1x5A stupid cuboid built just for the sake of completeness.
1x2x2It is not a boob cube but a boob can solve this one too.
1x2x3A very simplistic cuboid but a must for completionists.
1x2x4A cuboid which can be viewed as combination of 1x2x2 and 1x2x3.
1x2x5A fully functional 1x2x5
1x2x7Another rather early case of cuboid going into large dimensions.
1x2x9Another case of twistypuzzle extremism. A proof-of-concept how far a mechanism can be driven.
